Switching On And Off; Overload Protection - Bosch GNF 35 CA Operating Instructions Manual

Dust Extraction
The machine must be operated
only with dust extraction. The
vacuum cleaner must be ap-
proved for the extraction of ma-
sonry dust.
In case of a malfunction of the
dust extraction system, stop
working, switch the machine off
and correct the malfunction of
the dust extraction system.
The machine can be plugged directly into the re-
ceptacle of a Bosch general-purpose vac with re-
mote starting control. The vac starts automati-
cally when the machine is switched on.
The vacuum cleaner must be suitable for the ma-
terial to be worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Bosch offers suitable vacuum cleaners for all ma-
terials to be worked.
For dust extraction using an external vacuum
cleaner, a suction adapter must be used in this
case (see accessories). Insert the suction
adapter and suction hose fixture firmly.

Initial Operation
Check for correct mains voltage: The voltage
of the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
The cutting unit must have engaged in
the uppermost position before the ma-
chine is switched on, so that the dia-
mond cutting discs do not touch the
workpiece.

Check the diamond cutting discs before
use. The diamond cutting discs must be
mounted in exact alignment and be able to
rotate freely. Carry out a test run for at least
30 seconds without any load. Do not use
any diamond cutting discs that are dam-
aged, out-of-balance, or vibrate.
Starting Current Limiting
As a result of soft starting, a 13-A fuse is ade-
quate.
Constant Electronics
The constant speed electronics hold the speed at
no-load and when under load nearly constant and
ensure uniform working performance.

Relieve the load on the machine immediately and
allow to cool for approx. 30 seconds at the high-
est no-load speed.
